Click the green flag and enter the amount of options there are. Then, enter the options one by one. Scratch Cat will say the options in a random order. I hope you are able to use this for something!
I always knew how to make a randomizer, it just was annoying. I would have to edit it to have the correct amount of options. Then, when one was called, I would have to go back into the editing and delete that one and change everything again. This does all that for you!
